This repository contains Golden Hardware Reference Design (GHRD) for Agilex 3 C-Series System On Chip (SoC) FPGA. The GHRD is part of the Golden System Reference Design (GSRD), which provides a complete solution, including exercising soft IP in the fabric, booting to U-Boot, then Linux, and running sample Linux applications. Refer to the HPS GSRD User Guide for the Agilex 3 C-Series Development Kit for information about GSRD.
The designs are stored in individual folders. Each design can be opened, modified and compiled by using Quartus Prime software. GHRD releases are created for each version of Quartus Prime Software. It is recommended to use the release for your version of Quartus Prime. These reference designs demonstrate the system integration between Hard Processor System (HPS) and FPGA IPs.
This is applicable to all designs.
- Hard Processor System (HPS) enablement and configuration
- Enable dual core Arm Cortex-A55 processor
- HPS Peripheral and I/O (SD/MMC, EMAC, MDIO, USB, I2C, I3C, JTAG, UART, and GPIO)
- HPS Clock and Reset
- HPS FPGA Bridge and Interrupt
- Note: The System MMU port in F2H and F2SDRAM bridges are disabled by default in baseline design, unless otherwise specified.
- HPS EMIF configuration (Inline ECC for LPDDR4 is enabled by default)
- System integration with FPGA IPs
- Peripheral subsystem that consists of System ID, Programmable I/O (PIO) IP for controlling PushButton and LEDs.
- Debug subsystem that consists of JTAG-to-Avalon Master IP to allow System-Console debug activity and FPGA content access through JTAG
- 256KB of FPGA On-Chip Memory
- Altera Quartus Prime 26.1
- Supported Board
- Agilex 3 FPGA and SoC C-Series Development Kit: Devkit User Guide

- Agilex 3 FPGA and SoC C-Series Development Kit: Devkit User Guide
- SUSE Linux Enterprise Server 15 SP4
Several tools are required to be in the path.
- Altera Quartus Prime 26.1
- Python 3.11.5 (only required when using command line to build)
This is recommended, when using command line to build.
export QUARTUS_ROOTDIR=~/intelFPGA_pro/26.1/quartusNote: Adapt the path above to where Quartus Prime is installed.
export PATH="$QUARTUS_ROOTDIR/bin:$QUARTUS_ROOTDIR/../qsys/bin:$QUARTUS_ROOTDIR/../niosv/bin:$QUARTUS_ROOTDIR/sopc_builder/bin:$QUARTUS_ROOTDIR/../questa_fe/bin:$QUARTUS_ROOTDIR/../syscon/bin:$QUARTUS_ROOTDIR/../riscfree/RiscFree:$PATH"'- To build the design using command line, refer to the README in each designs for instructions to run the desired make command.
- Launch Quartus.
- Open the project. Example: a3cw135-devkit-oobe/baseline/top.qpf
- Click the play button to compile the design.
- The compiled sof can be found in output_files folder of the project path.
- Command line and Quartus GUI should not be used intertwined.
- Mixing both design build flows might not generate some fileset correctly and fail the build.
Refer to the individual readme for details of the design.
